ALBERT DAVID, on cnrcnco manure, T0, nrr' -Ir Inc," for nnrenrs,

To all whom it may concern:

Be it .lmown that I, Annnn'r :DAYIID a citizen of the United States and a resident of Chicago Heights, Cook County, State of ,Illinois,; have invented an Improvement in Coloring Compositions, of which the following is a specification.

Myn esentin n el e t coloring, dyeing or tinting substances, particularly in ,liquid or paste form,and also to materials, especially of a saponaceous character,which inay be successfully and practically employed as carriers for the dyes employed in [the manufacture of the aforesaidliquid or paste, coloring or equivalent compositions.

Itis an object offthe present invention to provide colo ing Substances of the character specified which shall be uniform in composition, which shall substantially avoid spotting and smearing of .the ,fabrics to which they are applied, and which shall also provide a dye in such a condition that it is already ,fullydissolvedand,in such a form as to render the use of sucli coloring substances highly convenient and economical.

For purposes of example I shall, in the accompanying specification, illustrative embodiment of my invention, it beinghow ver, clearly understood that ,my invention is not embodiment which herein describedfor purposes of illustration only.

For the coloring, tinting or dyeing sub stance I inay use any suitable dyestuff, pref erably a water-soluble dye, whether acid, direct orbasic. Vhile varying amounts of this dyestufl may be employed, I prefer that the finished composition shall contain about one per cent by weight of the dyestuff.

Intimately mixed with the other ingredients of the coloring composition, particularly the dyestu'lf, is a saponaceous substance preferaloly comprising ordinary pure soap such as the soaps known to the trade under the names Ivory soap, Lux Fairy soap, or castile soap. This soapserves to give body to the coloring composition, particularly where it is desired, as is preferred, to have the coloringcomposition in the form of a paste. The soap also serves to exercise a cleansing action on the fabric being colored. dyed or tinted, and serves at the same time to help fix the dyestuif on the fabrics to which it is being applied. While varying amounts of the Saponaceous body or [forth one limitedgto the illustrative w W rririmois, nssrenon, BY Mnsnn Assrennnw ronxj; ANQYTJA. conrona'rron or nnw yoax.

soap may be employed, I preferto use about one p er cent by weigl'itcf the soap inthe ,finished composition.

:Inorpler to substantially completely dissolvethe dyestuff rather than to provide the in the form ofan undissolved ,or solid suspension, with consequent spotting and smearing and other disadvantages, I prefer to eniploy enough of aliqnid carrier, such ,water, to completely dissolve the dyestufl' and to dissolve the soap, or,at leastto convert the final mixture into a paste if aliquid is not desired. For this purposeiI. prefer to employ water inun amount, for .example, ofaboutsixtywight per cent by weight of tl e finished composition. It will be :noted ,tliatthewater and thesoap together form a liquidorpaste saponaceous body or carrier in which the dyestuff is substantially com pletely and truly dissolved. h

I have,discoyered that a ,liquidor paste ins ribe po sess h unde rabl prop y that it cakes or hardens on' exposure, particularly on ontact with the air, a condition hardly to be avoided in ,the ordinary use and manipulation of suclrcolorinlr substances. .Ii prderto avoid-thisui 'rahle condition andin prder to. provide further means for effecting a more ,or ,less ,coniplete solution, of p, the dyestuff in the ,linishd coniposition I prefer to en'iploy a hygroscopic substance, preferably in .liqu id form, sucl 1. v as g'lycerine. in an amount, for example, equaling about thirty per cent by weight of the finished composition. I find that this substance not only prevents caking and solidification on exposure but even prevents a more or superficial drying of the composition and prevents also the undesirable insoluble soap film which would otherwise form on the composition, as on exposure to the air, andwhich would thus interfere with the convenient and successful application of iug substance holding the dyestufl in true solution. This result is helped by the pres coloring substance ofthecharacter thus far ll Ii once of the glycerine, which acts as a par tial solvent for the dyestull, althoiugh the dyestufls generally employed are not as soluble in glycerine as they are in water. However, this additional solubility enables the product to be made up to the desired coloring strength due to the partial solubility of the dyestult in the glycol-inc.

The ad *antages oi the present composition are numerous. Due to the dyestull being present in the composition in the form of a true solution, the product is uniform and may be :liully standardized. In this Way the uncertain and variable results of the coloring compositions in solid powder or soap form, hitherto employed in the art, are entirely avoided and overcome. The spotting so frequently met with in powder coloring or tinting substances is avoided and the smearing generally resulting from the use of coloring or tinting solid. soaps is also avoided.

The composition bein in the form oi a liquid or paste may be reaiilily packaged in collapsible tubes, which is a. distinct advantage since these substances, due to their great coloring power and the nodesirability of spreading except on the fabric, should be contained within receptacles from which they can be cleanly and economically distributed. The presence 01 the hy.: oscopic substances, particularly the glycerinc, the

use of which is preferred, ass ts the Water or othcr liquid carrier in keeping the dyestutl in perfect solution and at the same time by reason of this hygroscopic action prcvents the carrier from solidifying and the contents of the tube from eaking, or harden ing. In ]')1Itl()l]lfllf,tl10 glycerine prevents the formation of an insoluble soap film rein orally consisting of stearic. oleic, or palmitic acid or combinations of the same, which film would interfere With the dispensing, ot the liquid or paste from the tube in which it is contained and would also interfere with the successful and uniform application of the coloring or tinting composition to the tabrio to which it is to be applied.

The dycstull beinf already in true solution and the composition preferably harinp been filtered la tore being lillcd into the tubes, so as to incrtaise its uniformity, the rcsnlts obtained are uniilorni and depcrnlable so that a ncat, clcan job may be made of the coloring or tinting operation by persons, such as housewives, ordinarily unsl'iilled in the manipulation oil? coloring :uibstam'cs.

The presence of the soap. substantially all in solution, not only lends body to the composition but serves also to cleanse the liabric and to ii); the dyest ull' on the fabric to which it is being applied. This action of the soap much facilitated by its being substantially all in solution and, by the dyestutl' itsclit' lit-h e; in solution. The soap serves also at the same time to remote any trace of hardness in the water in which the (adoring:- or tinting opcratitni takes plac irhirh hardness would serve to inlcrl cre with the lixingol the dycstull' on the fabric.

It is, elf com-so, to be understood that my invention is not limited to the particular embodiment thereof herein shown and described.

hat I claim is:

.r lluid, coloring, dyein position comprising. in f'fOIDlJillFll'lOll, a an ionaccous body, a liquid carrier. n lyccrine in sullicient quantity to sullslaulially prcvent calcing of the mixture on exposure to the air, and a dye dissolved partly in said liquid carrier and partly in said glycerinc.

In testimony whereof, I have signed my name to this specification this 18th day of Ti lay, 1991.
